Problem

Conventional baby strollers lack a convenient and hygienic diaper-changing solution, as existing portable changing stations are often cumbersome, difficult to assemble, and require additional space and weight, making them impractical for everyday use.

Innovation Solution

A convertible baby stroller with a foldable and easily assembled changing station integrated into the stroller design, featuring a hinged frame, adjustable legs, and a waterproof surface that can be extended from the stroller to provide a clean and secure changing area, which can be easily stored and carried.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If portable changing stations are used, then diaper changing can be done away from home, but they are awkwardly shaped and complex to assemble

Engineering Contradiction:
Improveease of assemblyVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The changing station is merged with the stroller by utilizing the stroller's existing seat structure. The seat can be opened to reveal a waterproof changing surface, eliminating the need for separate portable changing stations and their complex assembly requirements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The stroller seat serves multiple functions: it can be used as a seating area for the baby and simultaneously transformed into a diaper changing station by opening the seat to expose the waterproof surface, providing multi-functionality without additional complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If portable changing stations are used, then diaper changing can be done away from home, but they take up valuable space and weight

Engineering Contradiction:
Improveaccessibility of changing stationVSAvoidweight of baby care equipment
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The changing station functionality is combined with the stroller structure, eliminating the need for separate portable changing stations that add weight. The stroller itself becomes the changing station, providing accessibility without additional weight burden.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The stroller seat provides dual functionality as both a seating area and a changing station, eliminating the need for separate equipment and reducing overall weight while maintaining accessibility for diaper changing away from home.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If conventional vinyl pads are placed on the ground, then diaper changing can be done anywhere, but the ground is dirty and unsanitary

Engineering Contradiction:
Improveportability of changing solutionVSAvoidhygiene and cleanliness
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The changing surface is integrated into the stroller seat structure with a waterproof material, providing a clean and sanitary surface that elevates the changing area off the ground, eliminating contact with dirty surfaces while maintaining portability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

A waterproof sheet or film forms the changing surface within the seat, creating a protective barrier that prevents contact with dirty ground surfaces while allowing the changing station to remain portable and integrated into the stroller.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

The present invention relates to a diaper changing station in connection with a stroller. The diaper changing station is attached to the stroller. When stored, the changing station does not detract from the appearance of the stroller. The changing station may be opened for use. The changing station is formed of a waterproof material for easy cleanup. In one embodiment, the changing station includes a bed and frame which are folded and stored below the seat of the stroller. The frame extends the bed from between the legs of the stroller to create a surface for the changing station. In other embodiments, the seat of the stroller is formed of multiple parts which are convertible from an upholstered seat to a changing station.
